1) The judgment of selecting COOL/HEAT is carried out as shown
below. When +1.5 exceeds against Tsh 10 minutes and after
thermo. -OFF, heating operation (Thermo. OFF) exchanges to
cooling operation. Description in the parentheses shows an example
of cooling ON/OFF.
When –1.5 lowers against Tsc 10 minutes and after thermo. OFF,
cooling operation (Thermo. OFF) exchanges to heating operation.
2) For the automatic capacity control after judgment of cooling/heating,
see Item 4.
3) For temperature correction of room temp. control in automatic
heating, see Item 3.

1-6. DRY operation
DRY operation is aimed to dehumidification.
In order to prevent lowering of the room temperature,
• Indoor fan speed is fixed to cooling L tap.
• Cooling capacity is restricted to low. When the room temperature is
lower than the setup temperature, the compressor is turned off.

AUTO
• COOL/HEAT operation mode is
automatically selected by Ta, Ts
and To for operation.
• The operation is performed as
shown in the following figure
according to Ta value at the first
time only. (In the range of Ts + α
–1 < Ta < Ts + α + 1, Cooling
thermo. OFF (Fan)/Setup air
volume operation continues.)
• α is corrected according to the outside temperature.
